Hey,
I'm talking moreso about the revision 1.02 boards and later. The A7V has very inaccurate temp readings by nature(see site in sig). To help rectify this, asus has implemented a "compensation" of +8C in newer 1004 and later BIOS' to help better approximate actual CPU core temp.
This approximation, in many instances of A7V temps, can be higher than core temp would be, which isn't necessarily a bad thing. Some other mb's don't even have compensation(MSI is one example), and these guys can be up to 10-20C too low in their cpu temp readings. the KT7, with its updated/compensated bios, still reads, at times, 10C too low.
Don't rely on the sensor reading as a solid reading, but use it to get a "relative" temp. IF that relative temp si reasonable, then you're fine.
